Bioavailability of copper and zinc was higher (P less then 0.05) in oak leaves and MMKH fed group (T3) as compared to T1, but similar to T2. Conversely, absorption of iron had the reverse trend and was reflected in serum Fe concentration. Hematological, biochemical, enzyme and hormonal profiles were not influenced by any of the treatments. The relative occurrence of estrus cyclicity and conception rate was more in groups T2 and T3, respectively, than other groups. It was concluded that feeding oak foliage-based diet containing 1.87% tannin along with customized mineral mixture developed for Kumaon hills improved certain nutrient utilization and reproductive performance as compared to local green grass supplemented with BIS-specific mineral mixture or MMKH.Mutations in diploid budding yeast occur in meiosis at higher frequencies than in cells grown vegetatively. Such meiotic mutations are thought to result from the repair of double-strand breaks (DSBs) in meiosis, during the process of recombination. Here, we report studies of mutagenicity in haploid strains that may undergo meiosis due to the expression of both mating-type alleles, MATa and MATα. We measure the rate of mutagenicity in the reporter gene CAN1, and find it to be fivefold higher than in mitotic cells, as determined by fluctuation analysis. This enhanced meiotic mutagenicity is shown to depend on the presence of SPO11, the gene responsible for meiotic DSBs. Mutations in haploid meiosis must result from repair of the DSBs through interaction with the sister chromatid, rather than with non-sister chromatids as in diploids. Thus, mutations in diploid meiosis that are not ostensibly associated with recombination events can be explained by sister-chromatid repair. The spectrum of meiotic mutations revealed by Sanger sequencing is similar in haploid and in diploid meiosis. Compared to mitotic mutations in CAN1, long Indels are more frequent among meiotic mutations. Both, meiotic and mitotic mutations are more common at G/C sites than at A/T, in spite of an opposite bias in the target reporter gene. We conclude that sister-chromatid repair of DSBs is a major source of mutagenicity in meiosis.

Surgeons often remain reluctant to consider laparoscopic approach in multiple liver tumors. This study assessed feasibility and short-term results of patients who had more than 3 simultaneous laparoscopic liver resections (LLR).

All consecutive patients who underwent LLR for primary or secondary malignancies between 2009 and 2019 were analyzed. After exclusion of major LLR, patients were divided into three groups less than three (Group A), between three and five (Group B), and more than five resections (Group C) in the same procedure. Intraoperative details, postoperative outcomes, and textbook outcome (TO) were compared in the 3 groups.

During study period, 463 patients underwent minor LLR. Among them, 412 (88.9%) had less than 3 resections, 38 (8.2%) between 3 and 5 resections, and 13 (2.8%) more than 5 resections. Despite a difficulty score according to IMM classification comparable in the 3 groups (with high difficulty grade 3 procedures of 16.5% vs. 15.7% vs. 23.1% in Group A, B, and C, respectively, p = 0.124), mean operative time was significantly longer in Group C (p = 0.039). Blood loss amount (p = 0.396) and conversion rate (p = 0.888) were similar in the 3 groups. Rate of R1 margins was not significantly different between groups (p = 0.078). Achievement of TO was not different between groups (p = 0.741). In multivariate analysis, non-achievement of TO was associated with difficulty according to IMM classification (OR = 2.29 (1.33-3.98)).

Since intra- and post-operative outcomes and quality of resection are comparable, multiple liver resections should not preclude the laparoscopic approach.

There is wide variation in choice of sedation and airway management for endoscopic retrograde cholangiopancreatography (ERCP). The aim of this study was to perform a systematic review and meta-analysis to investigate safety outcomes of deep sedation with monitored anesthesia care (MAC) versus general endotracheal anesthesia (GETA).

Individualized search strategies were performed in accordance with PRISMA and MOOSE guidelines. This meta-analysis was performed by calculating pooled proportions using random effects models. Measured outcomes included procedure success, all-cause and anesthesia-associated adverse events, and post-procedure recovery time. Heterogeneity was assessed with I

statistics and publication bias by funnel plot and Egger regression testing.

Five studies (MAC n = 1284 vs GETA n = 615) were included. Patients in the GETA group were younger, had higher body mass index (BMI), and higher mean ASA scores (all P < 0.001) with no difference in Mallampati scores (P = 0.923). Procedure success, all-cause adverse events, and anesthesia-associated events were similar between groups [OR 1.16 (95% CI 0.51-2.64); OR 1.16 (95% CI 0.29-4.70); OR 1.33 (95% CI 0.27-6.49), respectively]. MAC resulted in fewer hypotensive episodes [OR 0.32 (95% CI 0.12-0.87], increased hypoxemic events [OR 5.61 (95% CI 1.54-20.37)], and no difference in cardiac arrhythmias [OR 0.48 (95% CI 0.13-1.78)]. Procedure time was decreased for MAC [standard difference - 0.39 (95% CI - 0.78-0.00)] with no difference in recovery time [standard difference - 0.48 (95% CI - 1.04-0.07)].

This study suggests MAC may be a safe alternative to GETA for ERCP; however, MAC may not be appropriate in all patients given an increased risk of hypoxemia.

Fluorescent imaging is an emerging technological tool that can guide surgeons during surgery by highlighting anatomical structures and pathology, and help with intraoperative decision making.

A comprehensive review of published literature was performed using the search terms "fluorescence", "imaging" and "colorectal surgery" in PubMed. Only clinical trials that were published in English were included in this review. Ex vivo and animal studies were excluded.

This review demonstrates the use of fluorescence imaging in colorectal surgery in four areas (1) assessment of tissue perfusion and vasculature; (2) assessment of tumour; (3) lymphatic drainage and (4) identification of the urinary tract. The most commonly used fluorescent dyes are nonspecific, such as indocyanine green and methylene blue, but there is increasing interest in the development of specific fluorescently labelled molecular markers.

Fluorescence imaging is a potentially useful tool for colorectal surgery. Early studies on fluorescence imaging have been promising but larger scale randomised controlled trials are warranted to demonstrate the effectiveness and benefits of using fluorescence imaging routinely. The development of molecular dyes that are specific to targets could significantly increase the potential use of fluorescence imaging during surgery.

Their binding on BlaC involves covalent bonding and noncovalent interaction. We introduce a hypothesis that the noncovalent interactions dominate the difference of binding free energies for covalent ligands based on the assumption that their covalent bonding energies are the same. MM/GBSA binding free energies calculated from the noncovalent interactions provided a threshold with respect to the experimental kinetic data, to select slow carbapenem substrates which were either constructed using the structural units of experimentally identified carbapenems or obtained from the similarity search over the ZINC15 database. Combining molecular docking with consensus scoring and molecular dynamics simulation with MM/GBSA binding free energy calculations, a computational protocol was developed from which several new tight-binding carbapenems were theoretically identified.With this case report we support our medical hypothesis that metreleptin treatment ameliorates starvation related emotional, cognitive and behavioral symptomatology of anorexia nervosa (AN) and show for the first time strong effects in a male patient with AN. Pimasertib datasheet A 15.9 year old adolescent with severe AN of eight-month duration was treated off-label with metreleptin. Hyperactivity was assessed with accelerometry. Visual analogue scales (VAS), validated self- and clinician rating scales and lab results tracked changes from baseline to end of the 24-day dosing period and a five-month follow-up. Substantial improvements of mood and eating disorder related cognitions and hyperactivity set in after two days of treatment. During dosing, sub-physiological testosterone and TT3 levels normalized; clinically libido reemerged. Weight did not increase substantially during the dosing period. During follow-up target weight was attained; mood did not deteriorate; hyperactivity ceased. The results substantiate the strong effects seen in female cases and underscore the need for a double-blind placebo-controlled trial to confirm the observed strong, multiple and rapid onset beneficial effects of metreleptin in AN.Methionine is one of the many amino acids in the soil. In order to study the role of methionine in acidic forest soil, the effect of methionine (Met) was compared with control together with addition of ammonium (Met + A), nitrite (Met + N), and glucose (Met + C) under 60% or 90% water holding capacity (WHC), because ammonium and nitrite are important factors in nitrification, and glucose affect the heterotrophic nitrification and nitrogen immobilization. We found that methionine addition significantly reduced NO3- concentration in acidic forest soil. Compared to Met, Met + A and Met + N treatments non-significantly enhanced nitrification; however, Met + C treatment decreased NH4+ concentration which suggested that soil autotrophic and heterotrophic nitrification were limited in the presence of methionine at 60% WHC. Further, our findings of 15N-labeled treatment showed the impact and priming effect of methionine was negative for NO3- concentration and positive for N2O emission, which were observed mainly from the soil N source rather than methionine. At 90% WHC, Met + C treatment significantly lessened concentrations of NH4+ and NO3-, nonetheless improved N2O compared to Met treatment. Therefore, besides the denitrification and dissimilatory NO3- reduction to ammonia, the immobilization might be the key factor to explain this decrease in NO3- concentration at 90% WHC, while these processes were induced with the C addition. This study indicated that the positive role of amino acids in soil N cycling might be overrated.
